About this condition
Sensorineural hearing loss involves the inner ear or auditory nerve pathways. Understanding speech in noisy environments or over the phone may become difficult, even when the ear canal appears normal.
What matters most
The type and speed of hearing loss are essential to the decision about care. Sensorineural impairment may not be visible on ordinary otoscopy; earwax or external-ear inflammation are different problems.
Symptoms and reasons to seek help
Patients may have trouble following conversation in background noise, reduced clarity of speech, unilateral hearing difficulty and sometimes tinnitus. A sudden change can be noticed immediately on waking or after an otherwise ordinary day.
Distinguishing similar conditions
Gradual decline can be assessed through a planned pathway. Sudden hearing loss over hours or days may be time-sensitive and should not be attributed to a wax plug without assessment.
How clinicians investigate
An ENT clinician examines the ear to exclude external or middle-ear causes and reviews timing and neurological symptoms. Audiometry and other hearing tests may be needed to define the type and degree of impairment.
Care and important limitations
Management and rehabilitation depend on confirmed cause, test results and how quickly care begins. Do not rely on ear drops or postpone assessment for weeks when hearing has suddenly deteriorated.
When emergency help is needed
Sudden hearing loss developing over three days or less during the past month requires urgent ENT or emergency assessment, ideally within 24 hours. If facial weakness, speech disturbance, severe imbalance or other stroke signs occur, call 103 or 112 immediately.

Frequently asked questions
Is sudden hearing loss always caused by earwax?
No. An urgent assessment is needed to exclude sensorineural hearing loss.
Is looking into the ear enough to confirm the diagnosis?
Not always. Hearing tests are often required to determine the type of impairment.
Can I wait several weeks if hearing suddenly worsens?
No. Sudden onset requires urgent evaluation because timing may affect treatment options.

A medical consultation is needed for diagnosis and treatment recommendations.
